Title: Connecting structure for circuit board of plasma display panel
Inventor: OKUNAKA MASAAKI
IPC: H01J17/18
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent migration occurrence of silver electrodes by arranging the silver electrodes of a plasma display panel(PDP) on the inside of both end sections of the copper electrodes of a flexible printed board (FPC). SOLUTION: When a PDP and an FPC are connected by an anisotropic conductive film(ACF), if the width of the silver electrodes 8 of the PDP and the width of the copper electrodes of the ACF are equal, the field intensity is increased between adjacent electrodes with little interval due to the tolerances of the PDP and FPC respectively and some positional drift at the time of connection, and silver is easily deposited on FPC wires when the relative humidity and temperature are high. Positional drifts of about 0.05 mm at maximum are generated at both end sections for the connecting width of about 100 mm.  The width of the silver electrodes 8 of the PDP is made narrower by 0.1 mm or above, or the width of the electrodes of the FPC is made wider by 0.1 mm or above, then the silver electrodes 8 of the PDP invariably exist on the inside of both end sections of the copper electrodes of the FPC, thus the migration occurrence time is sharply extended, and the reliability of a product is improved.

Filed: 1990-11-14
Abstract: PURPOSE:To prevent a semiconductor substrate from being etched at the part of a contact hole when an etching operation to form a gate electrode is executed and to prevent a groove from being formed by a method wherein a first conductor film and a second conductor film are patterned and the gate electrode which is overlapped with the end part of a gate insulating film is formed. CONSTITUTION:A resist pattern 8 for electrode formation use is formed, by lithography, on a high-melting-point metal silicide film 7 in such a way that a contact hole C for contact use is covered completely. The high-melting-point metal silicide film 7 and polycrystalline Si films 6, 4 are etched sequentially in a direction perpendicular to the surface of a substrate by an RIE method; after that, the resist pattern 8 is removed. Thereby, gate electrodes G1, G2 of polycide structure are formed. At this etching operation, the contact hole C is covered completely with a part corresponding to the gate electrode G1 in the resist pattern 8, and a semiconductor substrate 1 is not revealed in the part of the contact hole C. As a result, the semiconductor substrate 1 in the part of the contact hole C is not etched and there is no fear that a groove is formed.

Title: Control of intermittent aeration type activated sludge method
Inventor: NAGAFUJI MASANORI
IPC: C02F3/30
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To cope with load variation without manually adjusting an aerobic/anaerobic time ratio or the like by measuring a respiratory rat of sludge for every intermittent aeration cycle, automatically setting an aeration interval time, and estimating a stoppage time of an aeration device so that an aerobic/anaerobic time ratio corresponds to a set value. SOLUTION: Initialization values are inputted (step 1). The start of control is ordered to start an initial operation mode (step 2). An initial operation collects a data for a respiratory rate Rr of sludge in a simple manner and calculates the Rr, the next aeration interval time is decided based on the calculation of the Rr, and an estimate operation mode is started (step 3). The estimate operation estimates a stoppage time of an aeration device from the Rr which was measured at the last cycle so that an aerobic/anaerobic time ratio set by aerobic time and anaerobic time is made to be within set values. If an appropriate Rr can be calculated, the estimation operation is carried out and the amount of aeration is regulated (step 4). However, this estimate operation depends on a peak value of the concentration of dissolved oxygen after the stop of the aeration device, and it can cope with load variation without hand regulation.
